Guadalupe River Trail, Park & Gardens

The 250-acre Guadalupe River Park is a three-mile ribbon park along the banks of the Guadalupe River in the heart of downtown San Jose from Highway 880 at the north, to Highway 280 at the south. 
It includes the downtown portion of the Guadalupe River Trail.
The northern section extends from Alviso at southern edge of the San Francisco Bay to Downtown San Jose - a great 9 mile opportunity to discover San Jose and Silicon Valley.  
The Guadalupe River Trail system is currently two disconnected trail systems (20 miles when completed).  The northern and central portions travel from the San Francisco Bay, through Silicon Valley and into Downtown San Jose (linking Gold St in Alviso to Virginia St in southern downtown).  A southern portion of the trail system extends from Chynoweth Avenue to Coleman Road and leads directly to the Lake Almaden and Los Alamitos Creek trail systems.
